As shown in Fig. 1, such rigid as to form a self-supporting frame which skeleton web columns 3 may lhave riveted or 65 may not only support the centering or molds bolted thereto the girders such as 1, to which for theoor panels, columns etc. but may the floor beams 8 may be bolted, riveted or also support the concrete elevating or dis-V otherwise connected (as by the stirrups in-. tributing` devices by which the concrete is dicated) so as to form a substantially rigid different floors'of the building. .Beams and 6 may beconnected sa that the construction girders of, this skeleton web type may adelevator? may thus be supported in con.- vantageously be used for concrete recnforceveying the Concrete and other materials to ment in floor constructionY since. such eX- the upper Aunfinished floors of theA building.

As shoivn in Figs. eland 5, rigid-skeleton Web columns of this character may in many eases be 'formed with additional stiffening cap constructions as to distribute the load throughout the diiiterent elements of this column reentorcement. As shown, thebody of the column may comprise tivo channel or I beam elements 3 having skeleton Webs such as the expandednietal skeleton Webs 2S shown in Fig. 4; and a heavy steel plate or cap plate 18 may be riveted on top ofthe column and secured to the channels and plates 19, 20. 27 so as to malte this cap plate rigid with all oi the'metallic column elef ments and properly transmit thereto the Weight of beams or girders such as t which may be secured to the cap plate as by the rivets 22 passing through the rivet holes 2l in the cap plate. In some cases it is advantageous to have suoli cap plates formed with one or moreholes through which the concrete may penetrate, such j as the hole 29 which facilitates the cari' ling up of the Concrete body of the colunm and more effectively uniting it to the adjacent concrete beam, floor and Wall elements of the building.

This invention has been described in conillustrative embodiments, forms, proportions, sizes, parts, materials and methods ot connection and use to the details of which disclosure the invention is not ofcourse to be limited since What is Claimed Vas new and what is desired'to be secured by Letters Patent is setforth in the appended claims.

In the claims the Word concrete is used to designate an cementitious material of to accomplish the objects desired.

I claim:
